Fatigue Reliability Analysis of Pressure-Reducing Valve

Advanced Materials Research, 2011
The paper is to develop a new approach to analyze the reliability of pressure-reducing valve basing on commercial software Ansys. After introducing the work principle of the pressure-reducing valve containing membrane, the mechanical model of the membrane acted by pressure caused by turbulence is established, base on which the simulated model built in ...

Dynamic Modeling of Pressure Reducing Valves

Journal of Hydraulic Engineering, 2003
Models are currently available for representing the dynamical behavior of most water network components. Such models are relatively simple, accurate and can be easily solved. However, there is no generally accepted dynamic model of a pressure reducing valve (PRV).

Synchronizer controlled by a proportional pressure reducing valve

2019 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2019
Proportional pressure throttling control characteristics of the synchronizer engagement process was studied. The model of the synchronizer and its electronically controlled hydraulic actuator was built, and then verified by the simulation and the test bench.

Modeling of Pressure Reducing Valves Revisited

WRPMD'99, 1999
The problem of simulating the steady state of water networks is very well known. There are many papers that have been written about this subject. Also there are software packages available for this purpose. However there is no explicitly described method to model the pressure reducing valves (PR\‘s).

Optimal Orifice Geometry for a Hydraulic Pressure-Reducing Valve

Journal of Dynamic Systems, Measurement, and Control, 1997
In this paper, the flow gain of a hydraulic pressure-reducing valve is examined. It is noted that classical linear-analysis is typically used to optimize the flow gain of hydraulic control-systems and that in practice this parameter is usually nonlinear.
